The new infra red screens have turned up along with a new front sensor to replace the shot one.
First test was air gun with ir switched on it didn't miss a shot.
Next out to the field .243 with similar weather conditions to before.
I tried without ir first,it didnt miss a shot so I never did need to turn it on.
Lastly down the range in bright head on sun light I could not get a reading.
I could not try ir because i left the power supply at home

Ian, yes a friend got it for me and did mention that a case was on the way for it, no sign of it yet though.

I feel quite upset - bought a shooting chrony years back - still on the original battery - provided its set up more than 6 foot from muzzle - provides faultless performance.

I want to have to resolve these issues that you guys have! Makes me feel like I'm not doing it right!!! Obviously didnt spend sufficient money [img]/ubbthreads/images/graemlins/smirk.gif[/img]

OK, tongue firmly in cheek as you can gather. Very satisfied with the basic model I purchased - folds small - believe the consistency racks up against other models costing x5 as much. Yes - means I have to manually log the velo reading as well as working out sd and mean - but hell, my calculator didnt cost much either. [img]/ubbthreads/images/graemlins/smile.gif[/img]

Jeza, I can understand the frustration you have been going through. I bought a CED about 3 years ago, after using the various Oehler models for the previous 30 years.

During the first 2 years the CED worked faultlessly, but about 9 months ago, I kept getting "0000" after each shot.

The Oz agent sent me another sensor, and bingo, it worked perfectly again for about 6 months, then 3 months ago, on 2 successive occasions, I got the "0000" again despite trying everything to make it register.

The Oz agent sent me another sensor, and bingo, fired 90 shots without 1 single failure. About 2 weeks ago, I went testing again, and in 35 shots could not get one to record. At the agents suggestion I returned the unit and sensors about 1 week ago, so it will be interesting to see what happens this time.

So far the service from the "Oz" agent has been excellent as the 2 sensors have been quickly replaced at no charge.

However, I have decided that if the problems persist, I will cut my losses and order an Oehler 35. Brian.

The weakness of most chronos are the screens. Early Oehlers had problems in some light conditions. The new Oehler 35 with its orange colored background that the sensor looks at has solved all my problems. Just can't beat an Oehler with a four foot spacing!!

waipiti13, I agree with your theory about screens being the main weakness.

The mystery problems with my CED appear to deepen, as the Oz agent said yesterday that my chrono worked perfectly under varying conditions during his testing. He also used it with the IR, and hooked my sensors up with another main unit, and it still worked perfectly.

However, thankfully he acknowledged that there is obviously a problem, but as yet he was not able to identify it.

The agent is going to return the chrono as is to me, and if I have further problems, will try to work out a deal on replacing the main unit.

I certainly recall using the Oehler Model 10 where you had to replace the 2 paper screens for each shot, then rotate the dial to get the count, and then look up the tables to convert to velocity. Brian.

I have had a CED Millennium for a few years now and the only time it didn't work right was when I placed the mini plugs in the wrong place. Labeled the sensor and cable ends and haven't mixed them up since. If I remember right, you can check the unit with a flash light. Flick the light over the first sensor and then the other if no reading go back to the first. If you get a reading then the cables are backwards. If not the unit is fubar.
